STARTING POSITION:
Get in the machine and place your body against the pad. Select the appropriate resistance on the weight stack. The feet pad should be behind your ankles (only a few inches above the heels), if is not adjust the machine lever. Grab the side handles of the machine. Contract your pelvic floor and core.
MOVEMENT:
Curl your right leg up as far as possible while you exhale. Hold 1 sec. Return to the starting position with a smooth movement, preventing moving weights from touching the rest of the stack. Repeat the movement for the specified amount of repetitions and then switch sides and repeat with the other leg.
